LOCOMOTIVE HEAD-LIGHT.

SPECIFICATION forming part of Letters Patent No. 272,245, dated February 13, 1883.

Application filed December 16, 1882. '(No model.) I

To allwhom it may concern Be it known that I, ARTHUR HARRIS, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Locomotive Head-Lights, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in means for displayingsigna-ls on locomotive head-lights and, briefly considered, it consists in casting light directly from the lamp and main reflector forward into reflecting-boxes opening into the frontof the case and rim, and thence transmitting the light by reflection back to the rear of the case outside the main reflector to reflecting-surfaces placed on angles, and thence through boxes projecting beyond the sides of the outer case for the display of signals at the fronts and sides of said boxes. The signals are thus made visible from the front and sides of the train.

In the accompanying drawings, Figure 1 is a sectional plan of my improved head-light on the line as w of Fig. 2, Fig. 2 being a side elevation of the invention.

Similar letters of reference indicate similar parts in both views. I

A is the outer case of the head-light or lantern, and at its rim. The lamp-burner is rep-- resented at b. At front upper portions of the outer case are placed boxes 0, which open at 0 into the front of the case, and also into the rim. The front walls of the boxes 0 are at their inner sides provided with mirrors or reflecting-surfaces c, standing somewhat at an angle, as shown, to cast back in the desired directions the light received thereon from the burner b. At the rear of the case A, at the upper and outer corners thereof, and-in the plane of the front boxes, 0, are placed boxes d, having curved rear walls, the inner sides of which are furnished with mirrors or reflectors e. The reflectors eare multiplied and suitably arranged to efl'ect a propercouvergence or concentration of the rays as a focus, and to effectively throw the light through the side I disclaim the invention set forth in Patent No. 225,299, granted March 9,1880, to Michael Nicholson; and also that described in Patent N 0.. 209,405, granted October 29, 1878, to William Kelley, reissued February 18, 1879, under N 0. 8,591, which patents cover the cutting ot' the rim. I also disclaim the cutting of the front of the outer case, which is shown and claimed in Patent No. 234,410, granted N ovember 16, 1880, to said Kelley.

I claim as my invention- 1. In a locomotive head-light, the combination of boxes opening into the front of the outer case and rim, and provided with interior reflecting-surfaces, and boxes opening into the rear wall of the outer case, having internal reflecting-surfaces and transparent glasses, through which glasses light is transmitted by reflection l'or signaling purposes, substantially as set forth.

.2. In a locomotive head-light, the combination of boxes opening into the front of the outer case and rim, and provided with interior reflecting-surfaces, and boxes opening into the rear wall of the outer case, having outer transparent signal-plates, and a multiplication of internal reflecting-surfaces set on angles to effect the convergence or concentration of the rays reflected back thereon, and to cast them through the transparent plates for signaling purposes, substantially as set forth.

In testimony whereof I aftix my signature, in presence of two witnesses, this 5th day of December, 1882.

ARTHUR HARRIS.
